Application filed. August 7, 1823. Serial No. 656,199.

prove and strengthen the construction of the supporting beams for bombshackles and remove the cause of failure and accidental release ofbombs. This has become of great importance on account of the fact thatbombs of greater and greater weight are being constantly designed foruse in warfare.

\Vith the above and other objects in view, th invention consists in thenovel construction, combination and arrangement herein shown, describedand claimed.

In the accompanying drawings.

Figure 1 is a front elevation of a bomb rack embodying the presentinvention.

Figure 2 is a side elevation thereof.

The present improvement relates to a bomb rack designed in such a waythat the load of the bomb is suspended from the release mechanism Cwhich is attached to the supporting girder D. The girder I) is carriedby two bomb shackle supporting beams X each of which is maintained uponthe airplane by fittings at the points B, B.

In the construction of each of the beams X, I employ a compressionmember 1 in the form of a plate and a tension member 2 also in the formof a plate, said plates being of any suitable length and width accordingto the weight to be imposed thereon. Between the members 1 and 2 thereare interposed torsion members 3 and 4 each shown in the form of achannel beam, the parallel flanges of which abut against the adjacentfaces of the members 1 and 2.

Enclosing the members 1, 2, 3 and 4 is a streamline housing 5 usuallyformed of sheet duralumin, the upper and lower portions of which, bearagainst the outer faces of the members 1 and 2. Through bolts 6 extendthrough the members 1 and 2 and through the flanges of the members 3 and1, also through the upper and lower parts of the streamline fairing 5,and also through the clips or fittings 7 connected to the opposite endportions of the beams X and also through the base fiangeS of thestabilizing members E which serve to steady the bomb, the outline ofwhich is indicated at F. The weight of the bomb carried by each beam isdivided so that some of this weight is taken by the streamline fairingandsome of it is taken by the aforesaid tension, com pression andtorsion members.

As a result of the construction and arrangementabove described, theinitial strength of the structure is higher for the same size and weightof bomb, no deterioration is experienced due to the effects of moisture,heat and other atmospheric c-onditions, exact strength may be moreeasily duplicated than in the case of a wooden beam, as the wood variesgreatly in strength due to treatment before being worked. The strengthof the mounting stations is higher, or in other words, in using woodenbeams extreme care must be exercised at the mounting points to preventthe fiber of the material from being broken down. This might be causedby tightening the bolts which are used to mount the brackets too tightlyor by tilting the brackets as they are drawn down. The safety factor ofthe improved beam is at all times apparent, that is, the approximatecondition thereof may be observed from the outside of the structure. Inthe case of a wooden beam this is impossible as the beam may beapparently all right as far as can be seen from the outside but may havedeteriorated to a great extent under the surface. This advantagefacilitates inspection of the racks while on the airplane.

I claim:

1. In a bomb rack, a. bomb shackle-supporting beam consisting of ametallic compression member, a metallic tension member, and parallelmetallic torsion members interposed between and united to said.compression, tension members and a metallic streamlined fairingenclosing the aforesaid beam members and means for securing the fairingto said beam.

In a bomb rack, a bomb shackle-supporting beam consisting of a metallicplate like compression member, a metallic plate like tension member, twochanneled torsion members interposed between said compres sion andtension members, a metallic stream lined fairing enclosing the aforesaidmembers and dividing the weight of the bomb with the said members, and aplurality of bolts interconnecting said members and said fairing.

3. In a bomb rack, the combination of a beam formed of metalliccompression and tension members and metallic torsion members locatedbetween the compression and tension members; a streamlined fairing forthe beam; a bomb supporting girder supported by said beam; stabilizersfor the bomb; and through bolts for'sec'uring the stabilizers and thefairing to the said beam.

4. In a bomb rack, the combination of a beam formed of metalliccompression and ,tGllSlOIl members, and metallic torsion members'located therebetween; a stream lined fairing for the beam; fittingsabove the beam for engagement with a support; and through bolts forsecuring the beam, fairing and fittings together.

In testimony whereof I afiix my signature.
